Game physicsComputer animation physics or game physics are laws of physics as they are defined within a simulation or video game, and the programming logic used to implement these laws. Game physics vary greatly in their degree of similarity to real-world physics. Sometimes, the physics of a game may be designed to mimic the physics of the real world as accurately as is feasible, in order to appear realistic to the player or observer. In other cases, games may intentionally deviate from actual physics for gameplay purposes.
Moteur physiqueUn moteur physique est, en informatique, une bibliothèque logicielle indépendante appliquée à la résolution de problèmes de la mécanique classique. Les résolutions typiques sont les collisions, la chute des corps, les forces, la cinétique, etc. Les moteurs physiques sont principalement utilisés dans des simulations scientifiques et dans les jeux vidéo. Certains sont également libres pour l'utilisation commerciale, à vérifier bibliothèque par bibliothèque. Box2D (Licence Zlib) Chipmunk (C, C++, Ruby, Python, OCaml.
Gravity anomalyThe gravity anomaly at a location on the Earth's surface is the difference between the observed value of gravity and the value predicted by a theoretical model. If the Earth were an ideal oblate spheroid of uniform density, then the gravity measured at every point on its surface would be given precisely by a simple algebraic expression. However, the Earth has a rugged surface and non-uniform composition, which distorts its gravitational field.
